Official Description

Severing adhesions of anterior segment, laser technique (separate procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Severing adhesions of the anterior segment using a laser technique is a specialized ophthalmic procedure aimed at addressing the presence of adhesions, which are abnormal fibrous bands that can form between the structures of the eye. These adhesions can restrict movement and impair vision. The procedure is performed as a separate intervention, meaning it is not part of a more extensive surgical operation. During the procedure, the eye is prepared with anesthetic eye drops to ensure patient comfort by numbing the area. A slit lamp, which is a microscope with a bright light, along with a gonioscopy lens, is utilized to provide a clear view of the anterior segment of the eye. This allows the physician to accurately direct the laser beam to the affected areas. Once the laser is activated, it precisely targets and severes the scar tissue, effectively releasing the adhesions and restoring normal function within the anterior segment of the eye. This procedure is crucial for improving visual outcomes and alleviating symptoms associated with adhesion-related complications.

1. Indications

Severing adhesions of the anterior segment using laser technique is indicated for the following conditions:

  • Adhesions in the Anterior Segment The procedure is performed when there are fibrous bands that restrict movement or cause discomfort in the anterior segment of the eye.
  • Impaired Vision Patients experiencing vision impairment due to the presence of adhesions may require this procedure to restore visual function.
  • Post-Surgical Complications Individuals who have undergone previous eye surgeries and developed adhesions as a complication may benefit from this intervention.

2. Procedure

The procedure for severing adhesions of the anterior segment using laser technique involves several critical steps:

  • Preparation of the Eye The first step involves administering anesthetic eye drops to numb the eye, ensuring that the patient remains comfortable throughout the procedure.
  • Use of Slit Lamp and Gonioscopy Lens A slit lamp is positioned to provide a magnified view of the anterior segment, while a gonioscopy lens is used to enhance visualization of the angle structures. This setup is essential for accurately targeting the adhesions.
  • Activation of the Laser Once the eye is adequately prepared and visualized, the laser is activated. The physician carefully directs the laser beam to the areas of scar tissue, ensuring precision in severing the adhesions.
  • Severing of Scar Tissue The laser effectively cuts through the fibrous bands, releasing the adhesions and restoring normal anatomical relationships within the anterior segment.

3. Post-Procedure

After the procedure, patients may be monitored for any immediate complications. It is common for patients to experience some discomfort or mild irritation in the eye, which can be managed with prescribed eye drops. Follow-up appointments are typically scheduled to assess the healing process and ensure that the adhesions have been adequately severed. Patients are advised to avoid strenuous activities and to adhere to any specific post-operative care instructions provided by their healthcare provider to promote optimal recovery.

RT Right side (used to identify procedures performed on the right side of the body)
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
LT Left side (used to identify procedures performed on the left side of the body)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
